Thermal Diffusion

For those of you attended the physics review, I want to apologize. I forgot to review an equation, though I'm not sure if it will be on the quiz tomorrow: thermal diffusion over an area.

The equation is simple enough:

P=KA((T1-T2)/L)

P is also seen as H on the equation sheet.
K is a constant, typically given, and different for various substances.
A is the area over which the heat is traveling.
T1 is the temperature of the hot side.
T2 is the temperature of the cold side.
L is the length over which the heat is traveling.
P comes out in calories per second (cal/s)
